FPS drops when items in inventory

Dear developers, as minecraft is my favorite game I want to play it with pleasure but there is no optimization on the GPU Power VR GE8320. The problem is this: when there is nothing in the inventory, then the FPS is in the aisles of 45-61, but this is great, but when I put something in inventory, the FPS drawdown to 20-25 begins. Also near the villages. I have a REDMI 6 CPU MEDIATEK Helio P22 GPU POWER VR GE8320. So on behalf of the users of Redmi 6 / 6A I appeal to you! Dear developers, optimize for our devices! We will be blogging to you! After all, MediaTek is also not a bad processor. thank
